Intelligence (AI), ManyNets (*)o abstracted over more than 20

network requirement dimensions considered within Sub-G1

o scored according to relative importance of specific network requirement [1 to 3 (low), 4 to 6 (medium), 7 to 9 (high), 10 (extremely high)]

Sub-G2: New Network Services (1/2)New Network Services [services below - defined in the approved Sub-G2

deliverable - focus on data plane services]

➢ In-time and on-time services -> see next slide

➢ Coordinated services -> see next slide

o guarantee of delivery of multiple flows in a dependent manner

➢ Qualitative communication services

o allowing applications to differentiate between different portions of packet payload

(chunks) and describe their relative priority to the network [discarding of lower priority

packets, if needed, can then reduce congestion and continuity of delivery of critical data

to the application, while minimizing the need for retransmission, can be ensured]

➢ Compound services (depending on more than a single constraint)
